He is playing Furth Challenger Qualies today.
First round against Delf Gohlke. To my mind this is a must win for Hirschmueller.
Second round would be against Meis/Torebko. He beat Torebko five months ago.
But his form isn't good tbh and Torebko is much better on clay than on an indoor court so i guess it won't be that easy like it was in January where he defeated him 2/4.
